A power window driving control device formed of a measuring device which measures time elapsed since closing of a window glass has been designated by a switch, a sensor which detects a completely closed state of the window glass, a current detecting device which detects that current flowing to a motor when the window glass is being closed exceeds a predetermined value, and a driving control device which effects one of stopping the motor and stopping the motor after driving the motor reversely for a predetermined time, in at least one of a first state, in which the current detecting device detects that the current flowing to the motor exceeds the predetermined value and in which the completely closed state of the window glass is not detected by the sensor, and a second state, in which the time elapsed since closing of the window glass was designated exceeds a predetermined time. Even if a foreign object exists on a path of movement of the window glass in a closing direction, the foreign object is not caught between the window glass and a window frame so that stability is guaranteed.
